Primes sample
Parallel version of the Sieve of Eratosthenes.
Building the example
cmake <path_to_example>
cmake --build .
Running the sample
Predefined make targets
make run_primes- executes the example with predefined parametersmake perf_run_primes- executes the example with suggested parameters to measure the oneTBB performancemake benchmark_primes- executes the example with suggested parameters to repeat performance measurements several times and report their relative error.make benchmark_primes_data- same asbenchmark_primessaving results intobenchmark_primes_data.csvfile.
Application parameters
Usage:
primes [n-of-threads=value] [number=value] [grain-size=value] [n-of-repeats=value] [silent] [-h] [n-of-threads [number [grain-size [n-of-repeats]]]]
-h- prints the help for command line options.n-of-threads- the number of threads to use; a range of the form low[:high], where low and optional high are non-negative integers orautofor a platform-specific default number.number- the upper bound of range to search primes in, must be a positive integer.grain-size- the optional grain size, must be a positive integer.n-of-repeats- the number of the calculation repeats, must be a positive integer; when it is greater than 1 then relative error will be calculated for them.silent- no output except elapsed time and relative errors.
